## What does the Q variable represent in the Hardy-Weinberg equation?

In this equation, p² is the predicted frequency of homozygous dominant (AA) people in a population, 2pq is the predicted frequency of heterozygous (Aa) people, and q² is **the predicted frequency of homozygous recessive (aa) ones**.

## How do you find q in Hardy-Weinberg?

To find q, simply **take the square root of 0.09 to get 0.3**. Since p = 1 – 0.3, then p must equal 0.7. 2pq = 2 (0.7 x 0.3) = 0.42 = 42% of the population are heterozygotes (carriers).

## What do PQ p2 2pq and q2 represent?

p2 +2pq + q2 = 1 Where p2 represents the frequency of the homozygous dominant genotype, q2 represents **the frequency of the recessive genotype** and 2pq is the frequency of the heterozygous genotype.

## What does the 2 in 2pq mean?

In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents **the frequency of the heterozygous genotype Aa**.

## What does the Q represent in the Hardy-Weinberg equation quizlet?

According to the Hardy-Weinberg equation, what does ‘q’ represent? **Frequency of the recessive allele**.

## What do p and q represent in the Hardy-Weinberg equilibrium equation?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate **the genetic variation of a population at equilibrium**. … where p is the frequency of the “A” allele and q is the frequency of the “a” allele in the population.

## Is P or Q recessive?

In the simplest system, with two alleles of the same locus (e.g. A,a), we use the symbol p to represent the frequency of the dominant allele within the population, and **q for the frequency of the recessive allele**.
